针对300MW汽轮机组转子轴承系统，在建立其8支承9节点集总模型的基础上，对轴系最左端面和发电机右端面的弯曲振动响应进行研究。为避免运行过程中受到的各种激励形式造成的扰动，设计了一种鲁棒轨迹控制器，保证了跟踪误差的一致终值有界。最后，通过模拟仿真对所提出的鲁棒控制方案与开环控制方案进行了比较，结果表明鲁棒轨迹控制具有更高的控制精度和稳定性。

英文摘要：

Aimed at the rotor bearing system of 300 MW steam turbogenerator set and on the basis of establishing its concentrated general model with 8 supportings and 9 nodes, a study was carried out on the bending vibration response of the most left end surface of shafting and of the right end face of generator. In order to avoid the turbulence caused by various forms of excitation fell under the operating course, a kind of robust track controller was designed, thus ensured the consistent final value of the tracing error to be bounded. Finally, a comparison was made between the being advanced robust controlling scheme and the open looped controlling scheme by means of simulated imitation, and the result showed that the robust track control possesses higher controlling accuracy and stability.
